2 Corinthians 1:12-24 (ESV)
Paul’s Change of Plans
12 For our boast is this, the testimony of our conscience, that we behaved in the world with simplicity  and godly sincerity, not by earthly wisdom but by the grace of God, and supremely so toward you. 13 For we are not writing to you anything other than what you read and acknowledge  and I hope you will fully acknowledge— 14 just as you did partially acknowledge us—that on the day of our Lord Jesus you will boast of us as we will boast of you.
15 Because I was sure of this, I wanted to come to you first, so that you might have a second experience of grace. 16 I wanted to visit you on my way to Macedonia, and to come back to you from Macedonia and have you send me on my way to Judea. 17 Was I vacillating when I wanted to do this? Do I make my plans according to the flesh, ready to say “Yes, yes” and “No, no” at the same time? 18 As surely as God is faithful, our word to you has not been Yes and No. 19 For the Son of God, Jesus Christ, whom we proclaimed among you, Silvanus and Timothy and I, was not Yes and No, but in him it is always Yes. 20 For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory. 21 And it is God who establishes us with you in Christ, and has anointed us, 22 and who has also put his seal on us and given us his Spirit in our hearts as a guarantee. 
23 But I call God to witness against me—it was to spare you that I refrained from coming again to Corinth. 24 Not that we lord it over your faith, but we work with you for your joy, for you stand firm in your faith.
